For hardware event-based sampling analysis on an Intel® Xeon Phi™ coprocessor based on Intel Many Integrated Core (Intel MIC) architecture, a sampling driver should be installed on the coprocessor cards to be sampled. Typically, the VTune Amplifier installs the drivers by default during product installation. If for some reasons the sampling driver was not properly installed on the Intel Xeon Phi coprocessor card(s), you may need to install the driver manually.
To install the sampling driver manually, run the following command lines as root or under sudo:
Copy the install files to a system location:
Start (or restart) the Intel Xeon Phi coprocessor service (this also restarts the sampling driver once the files are copied in the previous step):
$ service mpss restart
$ micctrl -w
You may receive error messages when restarting the service. Please refer to the Intel Manycore Platform Software Stack (Intel MPSS) documentation for details.
To uninstall the sampling server and driver on systems with the micboot-enabled Intel MPSS, run the following commands as root or under sudo:
$ service mpss stop $ sep_micboot_uninstall.sh $ service mpss restart $ micctrl –w
